摘要：

      目的：通过对绝经后妇女进行16周的振动训练，研究振动刺激对绝经后妇女平衡能力的影响。方法：21例50—63岁绝经后妇女随机分为实验组和对照组，采用Postural Equa平衡分析系统测量平衡能力等各项指标。实验组采用振动干预，对照组不接受任何干预。振动方案为：频率30—45Hz、20min/次，3次/周，连续16周。结果：组内对比，实验组在实验后，在闭眼状态下，压力中心（COP）指标中的Y值、最大摆幅（ML）值、线形图面积（AREA）值都明显低于实验前，分别下降7.33mm、8.33mm、16.67mm（P<0.05）；在睁眼状态下，其他各指标差异不明显。组间对比，实验组与对照组在实验前后，在睁眼和闭眼状态下静态平衡指标COP、TL、ML和AREA也未见有明显改变（P>0.05)。结论：16周的全身振动训练方案可以明显改善绝经期妇女的静态平衡功能。

Abstract:

      Objective: To investigate the effects of vibration stimulation on balance ability in postmenopausal women. Method: Twenty-one postmenopausal women were randomized to either vibration group or control group. Balance ability were measured. The vibration group consisted of a 16 weeks vibration training(30—45Hz, 10min, 3 times per week). Result: In vibration group after experiment when the subjects closed eyes static central of pressure（COP） Y, maximal length of swinging pathway (ML) and Area of swinging pathway（AREA） reduced significantly (P<0.05). But no significant changes of other indices of balance were observed between both groups. Conclusion: Sixteen week vibration training can improve postmenopausal women′s static balance ability.
